Features

● Small Size and Light Weight● High performance, reliability, and long life are assured.● Maintains High Vacuum● High-alumina ceramics provide superior mechanical strength and easy degassing.● High speed interruption and short arcing time.● The LS Vacuum Interrupter can meet all IEC, ANSI and NEMA performance standards.

Characteristics

StructureVacuum Interrupter consists of a ceramic insulator, two end plates, arc shield, bellows, a movable and fixed electrode, and contact set. The ambient gas pressure within the evacuated tube is approximately 10-6 torr.

Operating

●In the closed position, normal current flows through the interrupter. When a fault occurs and interruption is required, the contacts
are quickly separated.
● The arc drawn between the surfaces of contacts is rapidly moved around the slotted contact surface by self induced magnetic effects, preventing gross contact erosion and the formation of hot spot on the surface.
● The arc burns in an ionized metal vapor, which condenses on the surrounding metal shield. At current zero the arc extinguishes and vapor production ceases.
● The metal vapor plasma is very rapidly dispersed, cooled, recombined, and deionized, and the metal vapor products are quickly condensed so that the contacts withstand the transient recovery voltage.
